Alright, I know what's going on now, and it looks like a problem with the Opensuse init script. In fact, the initrd for the Xen enabled kernel got a *different* init script than the one for the non-Xen one. The difference being:
--- /tmp/testing/init 2007-07-24 15:53:58.000000000 +0200 +++ /tmp/xentest/init 2007-07-24 15:54:16.000000000 +0200 @@ -308,6 +308,9 @@ fi fi

The missing piece then is the innocent little line:
/init: line 311: /proc/xen/capabilities: No such file or directory
appearing on my screen during boot ... BOOM!
If I just diligently type all the skipped modprobe commands
$ modprobe scsi_mod $ modprobe sd_mod $ modprobe processor $ modprobe thermal $ modprobe libata $ modprobe ahci $ modprobe pata_marvell $ modprobe scsi_transport_spi $ modprobe aic7xxx $ modprobe fan $ modprobe edd $ ^D
into the fallback shell by hand, the system comes up without further ado.
So there, case solved. Now you sort it out who's to fix what. :-)
Thanks, Tilman
